Abstract
The utility model discloses a new and old concrete shearing resistant connection node for a foundation slab embedded in a concrete support, wherein a scabbling layer is arranged on the surface of the concrete support. As the scabbling layer is arranged on the surface of the concrete support, new concrete and old concrete are combined tightly through peeling scabbling, and the shearing resistance is effectively improved to ensure that the foundation slab and the support act well in combination with each other.
Description
Technical field
The utility model belongs to the building technical field of civil engineering, relates to a kind of shearing resistance connected node, is specifically related to a kind of ultra thick sole plate construction that is used for, and particularly concrete supports the new-old concrete shearing resistance connected node of embedded sole plate.
Background technology
The conventional way of sole plate construction is behind bottom slab concreting, again supporting removal.When sole plate is ultra when thick, the bottom support together is positioned at the base plate absolute altitude, according to conventional way, after bed course is built, needs carry out bottom slab concreting to one supporting removal in bottom again.At this moment, because not have the supporting cantilever end long in the retaining wall bottom, be unfavorable for the Deformation control of foundation ditch.In addition, dismounting of supporting and scarfing cinder also are unfavorable for material-saving and waste duration.In the time of can effectively avoiding present conventional sole plate job practices to construct ultra thick sole plate through the mode that adopts concrete to support embedded sole plate, the Deformation control ability of foundation ditch a little less than, be unfavorable for material-saving, and speed of application waits defective slowly.But adopt concrete to support embedded sole plate and since base plate with support between new-old concrete combines not tight, thereby cause base plate relatively poor with the support shear resistance, can not finely get phenomenons such as acting in conjunction, finally influence the quality of sole plate.
The utility model content
The utility model technical problem to be solved provides the new-old concrete shearing resistance connected node that a kind of concrete supports embedded sole plate, with the new-old concrete between solving sole plate and supporting combines tight, shear resistance is relatively poor, can not be fine must acting in conjunction etc. problem.
The technical scheme of the utility model technical solution problem is following:
A kind of concrete supports the new-old concrete shearing resistance connected node of embedded sole plate, it is characterized in that: the surface of supporting at said concrete is provided with the cutter batt.
Can know by above disclosed technical scheme; The utility model concrete supports embedded sole plate new-old concrete shearing resistance connected node and through the external surface that supports at concrete the cutter batt is set; Tight through " peeling " thereby the cutter hair combines new-old concrete; And effectively improve its shear resistance, guarantee that base plate and support can finely get acting in conjunction.
Description of drawings
Fig. 1 is the utility model new-old concrete shearing resistance connected node figure;
Fig. 2 is an A-A section structure sketch map among Fig. 1.
Reference numeral is following:
1, concrete supports 2, cuts a hole batt
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to detail.
Like Fig. 1, shown in 2, the utility model concrete supports the new-old concrete shearing resistance connected node of embedded sole plate, on the surface of said concrete support 1 cutter batt 2 is set.
Further, the degree of depth of said cutter batt 2 is 4～7mm.The preferred cutter hair degree of depth is 5mm.The cutter hair spacing of said cutter batt is 80～120mm.Preferred cutter hair spacing is 100mm.Stayed surface concrete chisel hair can carry out after support is built 12 hours.Behind cushion construction, carry out the work of support base cutter hair again, and the fragment under will cutting a hole is removed clean.
The preferred embodiments that the above is merely the utility model is not the protection domain that is used for limiting the utility model, and every equal conversion of being done according to the utility model claim is all within the protection domain of the utility model.
Claims (3)
